Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Water flows through a turbine as shown in figure, where the pipeline upstream of the turbine has a diameter of 1.2m and the downstream pipeline has a diameter of 1.7m. The inflow section of the upstream pipeline is 4 m above the outflow section of the downstream pipeline. When the flow through the turbine is 6 m³/s, the pressure at the inflow section is 450 kPa, the pressure at the outflow section is -30 kPa, and the head loss between these two sections is estimated as 20 m. What is the power being delivered to the turbine? 450 kPa 6 m³/s 1.2 m Turbine 4 m -30 kPa 1.7 m
Consider water flow through a horizontal, short garden hose at a rate of 30 kg/min. The velocity at the inlet is 1.3 m/s and that at the outlet is 11.75 m/s. The hose makes a 180° turn before the water is discharged. Disregard the weight of the hose and water. Taking the momentum-flux correction factor to be 1.08 at both the inlet and the outlet, the anchoring force (in N; hint: the answer is a negative number) required to hold the hose in place is ?
Water at 20 oC is pumped at a rate of 9.0 m3/h from a large tank resting on the floor(open to the atmosphere) to the top of an absorption tower, 5.0 m above the floor.

Find the minimum water level in the tank thatyou can achieve with a pump with that power.
A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
Lane has two pipes connected to each other that transport water because he is very thirsty. The given density of water is ρ = 997 kg/?3. The flow rate of water through the pipes is R = .009463522m^3/s, but they have different diameters. The first pipe has a measured pressure P1 =12.927 MPa and a velocity of v = 28.894 m/s.

In a hydroelectric power plant, water at 20℃ is supplied to the turbine at 1.2 m3/s through a 200 m long, 0.35 m diameter cast iron pipe.

A vehicle travelling at 100 km/h has air passing through its radiator at the rate of 100 kg mol per minute. The hot water from cooling the engine is circulated through the radiator at the rate of 10 L per minute, and as it passes through the radiator it is cooled from 78 °C to 32 °C. Assume the car is in good condition so the radiator has no leaks and the air and water do not contact. Given the heat capacity of the air is 1.0035 J·g-1·K-1, what is the temperature of the air exiting the radiator (assume air has a molecular weight of 29 g·mol-1).
In Figure 1, a reducing elbow is used to deflect water flow at a rate of 18 kg/s in a horizontal pipe upward 40o while accelerating. The elbow discharge water into the atmosphere. The cross sectional area of the elbow is 120 cm2 at the inlet and 10 cm2 at the outlet. The elevation difference between the centers of the outlet and the inlet is 50 cm. The weight of the elbow and the water in it is considered to be negligible. If the density of water is 1000 kg/m3 and momentum-flux correction factor is 1.03, determine: - The velocity of water at the inlet and outlet and - The gage pressure at the center of the inlet of the elbow
